Abstract (en)

A lens unit (15) and a sensor unit (16) are held by a lens holding mechanism (44) and a sensor shift mechanism (45). As the sensor unit (16) is moved in a Z axis direction on a second slide stage (76), a chart image is captured with an image sensor (12) through a taking lens (6) so as to obtain in-focus coordinate values in at least five imaging positions on an imaging surface (12a). An approximate imaging plane is calculated from the relative position of plural evaluation points which are defined by transforming the in-focus coordinate value of each imaging position in a three dimensional coordinate system. The second slide stage (76) and a biaxial rotation stage (74) adjust the position and tilt of the sensor unit (16) so that the imaging surface (12a) overlaps with the approximate imaging plane.
